Hello,
First of all, I have a PC running Windows 7, which is a Toshiba Satellite L550-10N. Since I connected a BenQ projector to it, I no longer have display on the screen (it’s black). However, it seems to be functioning normally, as the lights turn on and the fan runs. I have managed to restart it a few times after multiple attempts, entering my password blindly and pressing keys like Windows+P and Fn+P. But you can understand that this solution is not viable, and sometimes I can't turn it on at all. I am therefore wondering how to resolve this issue so that my computer can boot with a normal display every time.
Thank you in advance!!!
Configuration: Windows 7 / Chrome 43.0.2357.65

Hi,
It's the Windows key and P, then press the up arrow three times to select the PC screen.
Turn off the PC, then unplug the power cable from the PC, then press and hold the power button for 30 seconds, then release it, plug the cable back in and turn your PC on.
If your screen is still black afterwards, restart in safe mode by tapping F8 at startup, and you'll need to restore the default display settings.
See you later
